WALTER L. WHITMAN, OF BRIDGEPORT, PENNSYLVANIA.

LAV'RD-COOLER.

SPECIFICATION forming part of Letters Patent No. 512,642, dated. January9, 1894.

Application filed January 14, 1893.

.To all whom it may concern:

Be it known that I, WALTER L. WHITMAN, of the borough of Bridgeport, inthe county of Montgomery, State of-Pennsylvania, have invented certainnew and useful Improvements in Lard and Liquor Coolers; and I do herebydeclare the following to be a description of the same, reference beinghad to the annexed drawings, making part hereof.

My invention relates to apparatus for changing the temperature ofliquids, and has particular reference to that class of such devicesadapted for cooling lard.

My invention consists in the construction and combination of parts ashereinafter de-' scribed and claimed.

In the drawings :-Figure 1, is a longitudinal vertical sectional view ofthe tanks, the other parts being in elevation; Fig. 2, a vertical crosssectional view of the tanks, showing in elevation the coil of pipe andvibrating apparatus.

A is the outer tank made of wood, sheet iron, or other desired material;B the inner tank, into which is placed the material to be treated; Otheinterspace, into which is injected the liquid designed to perform partof the'function of changing the temperature of the contents of innertank B. Thelatter is preferably made of iron plate, or thick sheet ironso as to be susceptible as a conveyer of the temperature of the liquidin space 0 to its own contents.

D is the liquid in space 0, fedfrom pipe E,

the flow being regulated by valve J; F a pipe to convey the excess ofinfiowing liquid from space 0 and the entrance to pipe F is located at apoint at which it is desired to maintain the liquid level.

G is the material to be treated, the temperature of which it is desiredto change.

H is a tank from which through nozzle and cook I the material G issupplied to tank B.

K is a coil, or series of vibrating pipes, sustained by lifts L andchains or bandsM from horizontal rod N, which latter, at the will of theoperator is revolved by rod 0 and hand wheel 0. Rod 0 is connected withrod N by the universal joint P Q Q Q are lugs and joints; S sustainingguides R R R, which latter are long slotted Serial No. 458,429. (Nomodel.)

' rods adapted to receive so much, or such parts ism, so as to permit ofbending and freedom of action of the coil in its rising and lowering inguides R R R.

The operation is as follows: The tank B is charged with the matter to betreated from tank or reservoir H through nozzle and cock I. While thismatter, if it is desired, can be heated, we will suppose it is desirableto cool it; because the employment of the active agents to change thetemperature may go to cool or to heat such matter. Heated lard in itsliquid state is supplied totank B, if it is desired to cool it. Coldwater is supplied from pipe E to space 0, the overflow passing offthrough pipe F, continuously. Cold water is sent through pipe P,continuously, and finds its exit through pipe P. Wheel U is set inmotion and, actuating one guide B, through the coil, actuates the otherguides and by means of connecting rod T, vibrates the coil K laterallythrough the mass under treatment in tank B. Thus stirring it and coolingit within said tank by a continuous current of cooling vapor or waterwhile the tank is conveying to the mass the cooling influence of theliquid 0 in acontinuous current. When the lard is cooled sulficiently tobe set the flow of the cooling liquids is stopped by shutting off thecooks and valves controlling their flow. The hand wheel 0 is then turnedto wind up the chains or bands M M, thus raising the coil K in guides RR R. When the coil is raised out of the mass treated the latter isremoved from tank B by buckets, siphons, or any of the means known toordinarily skilled mechanics, which require no special description here.

What I claim as new is-=- 1. A temperature regulator forliquids,comprising in its construction a tank, a coil or connectedseries of pipe, avertically movable support for said pipe, flexibleconnections from said coil or series to supply and discharge pipes,means for raising and lowering said support, and independent means forvibrating said coil or series of pipe and support relatively to thetank, for the purpose set forth.

2. A temperature regulator for liquids, composed of a tank, adapted toreceive the liquid under treatment, a vibrating coil, or connectedseries of pipes,with flexible connecting tubes P P, adapted to injectand carry off the agent regulating the temperature of the contents oftank 13; vibrating mechanism R R, T U, to throw said coil from side toside of said tank, guides R R to direct the upward and downward movementof said coil; bands M M and rod or Winding agent N to take up said bandsM and raise said coil from the material under treatment, substantiallyas described.

3. A temperatu re regulator for liquids, com- 20 posed of a tank B,adapted to reeeive the liquid under treatment; a vibrating coil orconnected series of pipes, with flexible connecting tubes P P, adaptedto inject and carry cit the agent regulating the temperature in 25 saidcoil of pipe; vibrating mechanism R R, T U, to throw said coil from sideto side of tank 13; outer tank A, with an interspace between it and tankB, whereby a temperature regulating agent may be floated in said in- 30
